One-handed split times

[YVK]

I am looking for relatively validated performance parameters for one handed splits, both for reduced-sized and high-probability targets.
For definition purposes, with 3x5 card at 7 yards two-handed I am calling splits under 0.40 sec an expert level, 0.40-0.60 sec advanced, 0.60-0.80 intermediate. For 8 inch circle at 7 yards two handed, less than 0.20 sec - expert, under 0.30 advanced, under 0.40 intermediate. All of that assumes 100% hit rate, no misses.
I am looking for numbers that you folks are considering expert/advanced/intermediate for splits SHO and WHO, at 3x5 and 8 inch circle, 7 yards, no misses.

here is six to the body and one to the head, from the transition, at 7 yards in 2.5 seconds SHO at a Rogers School video on You Tube (not me, but I wish it was)
